elements hit this detector. this detector will measure the energy of the rhodesian itself. this sample, we put this-to radiation itself. and with the high sensitivity measurement. our samples are no currently taking a measurement within this cave. this is our detector. will enter it into a work computer the background that you would normally would see it. in this region, 600-672 gamma rays. that is one of the possible isotopes that we could see coming up from japan. i do not think that we should be concerned because we cannot expect anything to get near any health impacts in the states. >>pam: dr. chivers says that it takes 12 hours to sample each air specimen. and as
